  • It can vary depending on how the store sets the machines up. I’m on the wrong continent to use Walmart ones, but there’s definitely variation in how paranoid and slow they are set here.

    I feel it’s one of those cases where if you’re familiar with them and can think like the person who designed/programmed them, it can work pretty well. If you get confused by unfamiliar card terminals or a phone doing an update, you’re in trouble.

    E.g. it uses an expected weight and tolerance for products going into the scales. If this is produce you’ve just weighed, it’s going to be pretty precise. Same goes for something really light like a toothbrush; a 50% margin on tens of grams is still not much. If it’s a prepacked bag of oranges, then the weight could be way off (add a whole orange over the expected weight) so it won’t alarm on e.g. you putting a reusable shopping bag on the scale with the oranges. This lets you skip the annoying use-your-own-bag process.

    Knowing and remembering which is the next button to hit helps a lot.

    I find they’re fine for <5 items especially if the store is busy, but for a full trolley, you’re better off with a lane just for staging reasons.








  • An awfully large number of things that are now considered ‘historical scenic attractions’ and ‘an integral part of the landscape’ were originally built entirely for practical purposes with almost no consideration for aesthetics. Especially bridges and other infrastructure. See also steam trains.

    But you try and build new infrastructure and everyone wants to spend 3x the cost on architectural design, screening, or tunnel it underground entirely.


  • It was an attempt to derail California (and other) High Speed Rail.

    Why would you build HSR if there’s something way faster/better/cheaper, you just need to wait 5 years? You’re going to look really dumb if you spend tens of billions on infrastructure intended to last more than a century, and then it’s obsolete before it’s complete.

    Similar story with Toyota perpetually claiming to have amazing batteries 3-5 years away, making every EV look like an expensive waste with no resale value.

    And a hydrogen economy, small nuclear reactors, or fusion power being 5/10/20 years away, removing the need to invest in transmission and generation.

    A major paradigm shift being right around the corner makes people choose short-term solutions, because you want to wait for the new thing to arrive before investing in ‘old tech’.

    The problem is most of it is lies, perpetuated by those selling the short-term-fix old tech.



  • The whole point of pronouns, I would argue, is to not need a separate set for every instance.

    Otherwise you may as well just use Dan/Dan/Dan’s/Danself conjugated for each name.

    Pronouns:

    • Are (generally) shorter than names, because there’s less need for them to be unique and they’re used more frequently.

    • Can be used even when you don’t know specifics about a person or object, or they don’t want to give out their name.

    • Everyone knows how to conjugate them, so once you know someone is a ‘they’, you can readily extrapolate to them, their, theirs.
